The present invention relates to a punching device, a punching die, a punching method, and a positioning and fixing method of a punching die suitable for use in punching a sheet-shaped object to be cut. Background art

[0002] For example, in order to perform punching on a workpiece such as a metal sheet, a printed board, a flexible board, or the like, a workpiece is interposed between a punch die and a die die, and a punch die is formed. Is fitted into the die hole of the die.

Conventionally, a drilling device as shown in FIG. 14 has been used for drilling a workpiece of this type (for example, see Patent Document 1).

The punching device will be described with reference to FIG. 14. The punching device 1 includes a punch die 2 and a die die 3.

[0003] As shown in Fig. 14 (a), the punch die 2 has a backing plate 4, a punch plate 5, and a stripper 6, and is provided at the lower end of a guide plate 7 via a mounting plate 8. Has been done. The guide plate 7 and the mounting plate 8 are configured to move up and down by driving a lifting mechanism (not shown). The knocking plate 4 is fixed to a guide plate 7 via a mounting plate 8. The punch plate 5 has a punch 5a that can pass through the stripper 6, and is fixed to the backing plate 4. The stripper 6 has a projecting portion 6a, and is disposed below the punch plate 5 so as to be able to move up and down.

[0004] The guide plate 7 is connected to a lifting mechanism (not shown) via a guide shaft 9. The mounting plate 8 is provided with a spring accommodating hole 8a for accommodating the compression spring 10. At the lower end of the compression spring 10, a stripper guide pin 11 for inserting the backing plate 4 and the punch plate 5 is attached. The stripper 6 is attached to the tip of the stripper guide pin 11.

[0005] On the other hand, the die 3 for the die has a die plate 12, as shown in FIG. 14 (b), and is arranged below the die 2 for the punch. The die plate 12 has a die hole 1 into which the punch 5a can be fitted. 2a is provided.

[0006] In order to use the punching apparatus 1 configured as described above to perform perforation on the object to be machined, the object to be machined (not shown) is placed on the die plate 12 of the die 3 for a die. Is carried out by lowering the punch die 2 previously arranged at the upper standby position.

In this case, when the punching die 2 descends, the projecting portion 6a of the stripper 6 comes into contact with the object to be cut on the die plate 12. When the punching die 2 further descends from this state, the projecting portion 6a of the stripper 6 presses the workpiece onto the die plate 12. For this reason, the punch 5a projects downward from the die plate 12 and fits into the die hole 12a with the stripper 6 pressed against the workpiece on the die plate 12, and the workpiece is perforated.

When the punching die 2 moves up, the punch 5a comes out of the die hole 12a of the workpiece while the stripper 6 keeps pressing the workpiece on the die plate 12. Therefore, a smooth drilling operation is realized.

Disclosure of the invention

Problems the invention is trying to solve

[0007] Incidentally, in the above-described punching device, a stripper is required to smoothly punch the object to be cut, so that not only the number of parts is increased and the cost is increased, but also the die structure is increased. Was complicated.

In addition, at the time of drilling, since the stripper presses the workpiece to the die plate, there is a problem that the workpiece is easily damaged and the quality reliability is reduced.

Further, at the time of drilling, it is necessary to raise and lower the entire punching die, so that there is a problem that it is not easy to speed up the drilling.

[0008] The present invention has been made to solve such a problem, and it is possible to reduce the cost and simplify the mold structure, improve the quality reliability, and further improve the reliability. It is another object of the present invention to provide a punching device, a punching die, and a punching method that can easily speed up punching.

Another object of the present invention is to provide a method of positioning and fixing a die for punching, which can simplify the operation of positioning the die for punching. Means for solving the problem

(1) A punching device according to the present invention includes a punching mechanism having a punching die and a die for punching for punching a sheet-shaped workpiece; Means for applying tension to a sheet-shaped workpiece interposed between the die and the die die, wherein the punching mechanism comprises a punch die and a punch die. It is a special feature that the punching mechanism performs the punching in a state where the gap between the die and the die is larger than the thickness of the sheet-shaped workpiece.

[0010] For this reason, according to the punching device of the present invention, the punching operation is performed in a state where tension is applied to the material to be interposed between the punch die and the die die. In addition, the bending of the sheet-like workpiece is effectively suppressed, and as a result, the punching operation is performed at a correct angle with respect to the workpiece, and the punch can be smoothly removed from the workpiece. For this reason, it is possible to perform the drilling in a state where the gap between the punch die and the die die is larger than the thickness of the sheet-shaped workpiece. That is, the stripper that has been required conventionally can be eliminated. Therefore, according to the punching device of the present invention, the number of parts can be reduced, and the cost can be reduced and the mold structure can be simplified.

In addition, since the drilling is performed in a state where the material to be pressed is in a non-pressed state, it is possible to reliably suppress the occurrence of damage to the material to be dried and to improve the reliability in quality. it can.

These effects are achieved by a punching device in which the punching device includes a feeding mechanism for feeding a roll-shaped workpiece into a sheet and a winding mechanism for winding the sheet-shaped workpiece into a roll. In this case, it becomes particularly large.

In addition, since the punching is performed in a state where the gap between the punching die and the die die is larger than the thickness of the sheet-shaped material to be punched, the punching die itself must be moved up and down during punching. It is no longer necessary and only the punch needs to be moved up and down, so that it is easy to speed up the drilling.

[0011] (2) In the punching apparatus according to the above (1), the punching mechanism may be configured such that the gap between the punch die and the die is 0.10 mm to 5. Omm. It is preferable to carry out The reason why the gap is set to 0.10 mm or more is that if the gap is set to less than 0.10 mm, it may be impossible to pierce a relatively thick material. From this point of view, the gap is more preferably 0.20 mm or more, and even more preferably 0.30 mm or more. The reason why the gap is set to 5.Omm or less is that if the gap exceeds 5.Omm, it is not easy to secure the positional accuracy between the tip of the punch and the die hole. Is not easy to maintain. From this viewpoint, it is more preferable that the gap is set to 3.Omm or less, and it is further preferable that the gap is set to 2.Omm or less.

[0012] (3) In the punching device according to (1) or (2), the punching mechanism may be configured to perform punching without a guide pin interposed between the punch die and the die die. It is preferable to carry out the following.

The positioning between the part and the die can be performed with high accuracy.

Accordingly, since the positional accuracy between the punching die attaching portion of the punching device and the punching die is increased, it is possible to enhance the accuracy of the punching position on the object to be cut. In addition, since the positional accuracy between the punching die and the die die is improved, it is possible to perform clear perforation without returning the slice. In addition, there is also an effect that a dedicated die position adjusting device for punching is not required, and the cost of the punching device can be reduced.

These effects are achieved by a punching device in which the punching device includes a feeding mechanism for feeding a roll-shaped workpiece into a sheet and a winding mechanism for winding the sheet-shaped workpiece into a roll. In this case, it becomes particularly large as in the case of the above (1) or (4). Further, by adding the features of the punching device of the present invention to the punching device described in (1) or (4) above, a more excellent punching device can be obtained.

The mold has a through hole for photographing that opens to the workpiece, and an image sensor for reading the position of the hole in the workpiece is provided on the central axis of the through hole. The feature is that.

Therefore, according to the punching device of the present invention, it is possible to read the punching position in the plane of the punch die and the die by the imaging device. Therefore, it is possible to shorten the horizontal movement time from the reading of the punching position by the image sensor to the position at which the punching die is reached, and the speed of the punching force can be increased. The reading of the drilling position can be performed with a directional force perpendicular to the object to be drilled, so that the reading accuracy can be improved.

The die has a plurality of punch holes, the die has a plurality of die holes corresponding to the plurality of punch holes, and each punch corresponding to the punch holes has a cam. By rotating the shaft It is preferable to be configured to be movable in hoistways different from each other.

With this configuration, by changing the rotation area of the cam shaft, any one of the plurality of punches can be selected and used for punching a workpiece.

(11) In the punching apparatus according to the above (10), the punch mold includes another plurality of punches including the center axis and arranged along a virtual plane different from the virtual plane. The die for a die further has a plurality of die holes corresponding to the plurality of the punches, and the punch die and the die mold have a plurality of punch holes. It is preferable that the punching device is detachably attached to a plurality of circumferential positions around a virtual reference line perpendicular to the upper surface of the punching die attaching portion of the punching device.

With such a configuration, a plurality of punches arranged in a desired direction can be selected and used for punching a workpiece by changing a mounting position in a punch die and a die die. it can.

The positioning between the mounting portion and the die can be performed with high accuracy.

(13) The punching method according to the present invention provides a punching device including a punching mechanism having a punching die and a die for punching a sheet-shaped workpiece. And a sheet-like workpiece interposed between the punch die and the die die. A punching method for punching a workpiece under tension, wherein a gap between the punch die and the die is larger than a thickness of a sheet-shaped workpiece. The drilling is performed in a state.

[0029] For this reason, according to the punching method of the present invention, since the punching operation is performed in a state where the workpiece interposed between the punch die and the die die is subjected to a tension, a sheet-like shape is formed. The deflection of the workpiece is effectively suppressed, and as a result, the punching operation is performed at the correct angle with respect to the workpiece, and the punch can be smoothly removed from the workpiece. For this reason, it is possible to perform perforation in a state where the gap between the die for punch and the die for die is larger than the thickness of the sheet-shaped object to be cured. That is, the stripper that has been conventionally required can be eliminated. Therefore, according to the drilling method of the present invention, the number of parts of the drilling device can be reduced, and the cost can be reduced and the mold structure can be simplified.

In addition, since the drilling is performed in a state where the material to be pressed is in a non-pressed state, it is possible to reliably suppress the occurrence of damage to the material to be dried and to improve the reliability in quality. .

In addition, these effects are achieved by a punching device in which a sheet-shaped workpiece is fed out of a roll-shaped workpiece into a sheet shape, and a winding mechanism for winding a sheet-shaped workpiece into a roll shape. In the case of a perforation device having the following, the size becomes particularly large.

In addition, since punching is performed in a state where the gap between the punch die and the die die is larger than the thickness of the sheet-shaped workpiece, the punch die itself needs to be moved up and down during drilling. It is sufficient that only the punch moves up and down, so it becomes easy to speed up the drilling.

A step of fixing the die to the perforation mold mounting portion, and a step of further lowering the positioning pin to release the fitting with the pin fitting hole and disassemble the perforation mold assembly. It is characterized by having.

[0031] For this reason, according to the method for positioning and fixing the punching die of the present invention, the positioning of the punch die and the die die and the positioning of the table and the die can be performed by a simple operation of raising and lowering the positioning pin. Positioning with a die can be performed with high accuracy.

Accordingly, the positional accuracy between the table and the die for punching is enhanced, so that the accuracy of the punching position in the object to be cut can be increased. In addition, since the positional accuracy between the punching die and the die die is improved, it is possible to perform a clear perforation without returning the section. In addition, there is also an effect that a dedicated die position adjusting device for a punch becomes unnecessary, and the cost of the punch can be reduced.

In between, a punching die assembly is formed with a spacer having a pin insertion hole and having a thickness of 0.1 mm to 5 mm in advance, and the die assembly for punching is disassembled. The step is characterized in that the spacer interposed between the punch die and the die is removed.

With this configuration, the size of the gap between the punch die and the die die can be reduced to a range of 0.10 mm to 5. Omm by a simple method using only a predetermined spacer. Can be controlled with extremely high precision. In addition, since it is not necessary to separate the punch die and the die die so that a predetermined gap is opened, the degree of parallelism between the punch die lower surface and the die die upper surface is extremely high. Can be. Furthermore, when the positioning pin is moved up and down, force is generated between the positioning pin and the pin hole and the pin fitting hole. There is also an effect that it is possible to prevent such a situation.

This also means that the dimensional difference between the inner diameter of the pin hole and the pin fitting hole and the outer diameter of the positioning pin can be set to an extremely small size. As a result, the relative positional accuracy of the punch mold and the die mold in the horizontal direction can be improved, which is effective in preventing the return of the section due to drilling and increasing the speed of drilling.

The dimension between the two legs 724A and 724B is set to be larger than the dimension of the workpiece W in the width direction.

[0048] Although not shown here, the die-mounting portion for punching has a die-mounting portion for punch and a die-mounting portion for die. The punch die mounting portion is provided on the frame 724, and the die die mounting portion is provided on the table 722.

The punching mechanism 800 has a punching die 810 and is arranged on the table 722 of the second table moving mechanism 720.

The punching die 810 includes a punching die 820 and a die die 830, and is configured to perform punching on the workpiece W.

As shown in FIG. 11, the punch die 820 includes a base 821, a plate mounting block 822, and a punch plate 823, and is entirely formed by a stepped (with a flange) block body. I have. And it is attached to the ceiling part 724C of the frame 724 via the chuck member 910 (see FIG. 5). At the center of the punching die 820, a step-shaped accommodation hole 820A that opens to the workpiece is provided. A light emitting element 840 (shown in FIGS. 8 and 9) for illuminating the workpiece W is accommodated in the accommodation hole 820A. Thereby, the illumination light from the light emitting element 840 is effectively used for illumination of the object W.

[0051] In the vicinity of the center of the punching die 820, the central axes of the two first punch-through holes 820B, 820C and the accommodation hole 820A arranged along an imaginary plane including the central axis of the accommodation hole 820A. Two second punch holes 820D and 820E are provided along another virtual plane orthogonal to the above-mentioned virtual plane. As shown in FIGS. 9 and 10, a pair of punches 850 and 851 are passed through the first punch through holes 820B and 820C. Also, as with the first punch through holes 820B and 820C, one set of the second punch through holes 820D and 820E. (Not shown) is inserted. The corners of the punching die 820 (the corners facing each other) are the outer peripheral portions of the first punching holes 820B and 820C and the second punching holes 820D and 820E, and are equally spaced from each other (180 °). ) Two pins mating in parallel in the circumferential direction with? L820F, 820G power S provided and level.

The punches 850 and 851 are connected to a cam shaft 870 rotated by a servo motor 860 via roller shafts 871 and 872 as shown in FIGS. The punches 850 and 851 are configured to be movable in different hoistways by rotation of the camshaft 870 driven by the servomotor 860. For this reason, by changing the rotation area of the camshaft 860, one of the punches 850 and 851 (the punch 850 in the present embodiment) is selected and used for the punching of the workpiece W. can do. The servo motor 860 and the camshaft 870 are provided on the ceiling 724C of the frame 724.

When the punches 850 and 851 are punches having the same diameter, for example, if the punch 850 is damaged during the drilling of the same diameter, the punch 851 can be used instead of the punch 850. The installation and removal and replacement of the 850 become unnecessary.

When the punches 850 and 851 are punches having different diameters (for example, a punch for drilling a through hole and a punch for drilling a guide hole), the punches having different diameters can be formed. Installation of punches 850 and 851 by changing the dawn target 'No need to replace.

As shown in FIG. 11 (b), the die for die 830 has a plate mounting block 831 and a die plate 832, and is entirely formed by a stepped (with a flange) block body. . Then, it is disposed below the punching die 820 and is attached to the tape holder 722 via a chuck member 911 (see FIG. 5). In addition, the die mold 830 is detachably mounted together with the punch die 820 at two circumferential positions around the central axis a. Therefore, by changing the mounting positions in the die 830 for the die and the die 820 for the punch, one of the two sets of punches 850 and 851 is selected and used for drilling the workpiece W. You can S.

In addition, by making the shape of the punch die and die die hexagonal or octagonal, It is also possible to provide three or four sets of punches for one punch mold.

As shown in FIG. 11 (b), the center of the die for die 830 is located on the central axis a of the accommodation hole 820A, and is open to the workpiece W side. A hole 830A is provided. At the corners of the die 830, there are provided pin holes 830B and 830C corresponding to the pin fitting holes 820F and 820G, respectively, and being arranged at equal intervals (180 °) in the circumferential direction. .

The die for die 830 (die plate 832) is provided with die holes (not shown) corresponding to the first punch through holes 820B and 820C and the second punch through holes 820D and 820E. I have. An image sensor 880 (shown in FIG. 8) for reading the position of the punched object W is provided on the center axis a of the through hole 830A in the die 830 for the die. As a result, the horizontal distance from the image pickup device 880 (through hole 830A) to each of the punches 850 and 851 has the same dimension, so that the punch 850, 851 (perforation die 810 ) Can be set to the same time as the horizontal movement time until the drilling position is reached.Also, the illumination light power by the light emitting element 840 is transmitted through the workpiece W and read by the imaging element 880, so that the drilling is performed. The reading of the position is performed effectively.

As shown in FIG. 5, FIG. 10 and FIG. 11 (b), the punching die positioning and fixing mechanism 900 has chuck members 910 and 911 and positioning pins 920 and 921. Then, in a state in which the punching die 810 is in the state of performing the punching, a gap G having a vertical dimension larger than the thickness of the workpiece W is formed between the punching die 820 and the die die 830. Has been

The vertical dimension of the gap G is, for example, 0.40 mm when the thickness of the workpiece W is 0.10 mm. The diameter of the punches 850 and 851 varies depending on the object to be punched. For example, the diameter is set to 0.10 mm 5. Omm.

[0058] Chuck member 910 is attached to ceiling 724C of frame 724, and chuck member 911 is attached to the center of table 722 in the width direction. Then, the punch die 820 is fixed to the ceiling portion 724C of the frame 724 by the chuck member 910, and the die die 830 is centered in the width direction of the table 722 by the chuck member 911 (below the punch die 820). ).

[0059] As shown in Figs. 10 and 11, the positioning pins 920 and 921 can be fitted into the pin fitting holes 820F and 820G of the punching die 820, and the pins of the die die 830. The through-holes 83 OB, 830C are formed by a cylindrical body that can pass through, and that fits into a positioning hole (not shown) provided in the table 722. At the lower ends of the positioning pins 920 and 921, there are provided elongated holes 920A and 921A, which penetrate in the pin radial direction and through which the eccentric shafts 930A and 931A of the pin operators 930 and 931 pass. The positioning pins 920 and 921 are configured to move in the vertical direction by rotating the pin operators 930 and 931, respectively.

[0060] Using the punching apparatus 100 configured as described above, punching is performed on the to-be-processed material W in the following manner.

First, the workpiece W is interposed between the punch die 820 (punch plate 823) and the die die 830 (die plate 832). In this case, a gap G (shown in FIG. 11) between the punch die 820 and the die die 830 is set to a size larger than the thickness of the workpiece W by the die positioning and fixing mechanism 900 for punching. ) Is formed.

Next, the feeding mechanism 300, the winding mechanism 400, and the table moving mechanism 700 (the first table moving mechanism 710) are driven synchronously to quantitatively move the workpiece W from the feeding side to the winding side. Supply. At this time, the gripping force of the fixed clamper 730 is applied to the object W, and the gripping force of the movable clamper 222 and the fixed clampers 232 and 233 is released.

[0063] Thereafter, the movable clamper 222 moves forward from the payout side to the winding side. At this forward movement position, a gripping force is applied to the workpiece W, and the fixed clamper 232 is gripped. And the gripping force by the fixed clamper 730 is released.

When the gripping force of the fixed clamper 730 is released, the movable clamper 222 moves back from the winding side to the payout side while applying the gripping force. As a result, the workpiece W is provided with tension by the movable clamper 222 and the fixed clamper 232. For this reason, the deflection of the sheet-shaped force-cured material W interposed between the punch die 820 and the die die 830 is suppressed. At this time, since the sheet-shaped material W is sandwiched between the upper roll shafts 744, 754 and the lower Lorenole shafts 742, 752, the bending is more effectively suppressed. It is in a state of being damaged.

Then, when the image sensor 880 detects a reference mark (a display mark for reading a punching position) of the workpiece W, the first table moving mechanism 710 drives the punching die 810 (punch). The die 820 and the die 830) are transferred to the perforation area.

Then, by driving the table moving mechanism 700, the punching die 810 is moved along two horizontal directions which intersect at right angles, and the punch 850 is moved up and down by rotation of the camshaft 870 to form the workpiece W. Perform perforation. In this case, by changing the rotation area of the camshaft 870, the punch 851 can be used for perforating the workpiece W instead of the punch 850.

In this manner, the perforated material W is pierced.

[0067] In order to eliminate the meandering movement of the workpiece W caused by perforation (extending and winding operation) over a long period of time, the lifting rollers 510, 610 of the tension mechanisms 500, 600 are appropriately raised and the workpiece W is lifted. It is preferable to release the tension applied to the material W.

[0068] As described above, the punching apparatus 100, the punching die 810, and the punching method according to the embodiment can obtain the following effects (A) to (E).

(A) Since the punching operation is performed in a state where the tension is applied to the workpiece W interposed between the punch die 820 and the die die 830, the sheet-shaped workpiece is processed. The deflection of the workpiece W is effectively suppressed, and as a result, the boring operation is performed at a correct angle with respect to the workpiece W, and the punch is smoothly removed from the workpiece W. For this reason, it is possible to perform perforation in a state where the gap G between the punch die 820 and the die die 830 is larger than the thickness of the sheet-shaped material W. That is, the stripper that has been required in the past can be eliminated. Therefore, the number of parts can be reduced, and the cost can be reduced and the mold structure can be simplified.

In addition, since the drilling is performed in a state where the workpiece W is in a non-pressed state, it is possible to reliably suppress the occurrence of damage to the workpiece W, and to improve the reliability in quality. You can also. In addition, since punching is performed in a state where the gap G between the punch die 820 and the die die 830 is larger than the thickness of the sheet-shaped workpiece W, the punch die 820 itself is used at the time of punching. It is not necessary to move up and down, and only the punches 850 and 851 need to move up and down, so that it is easy to speed up the drilling.

[0070] (B) Since the frame 724 is a gate-shaped frame having two legs 724A and 724B facing each other and a ceiling 724C connecting the two legs 724A and 724B, the punch die is used. The rigidity of the frame 724 to which the 820 is attached is reliably increased.

Therefore, the position accuracy of the punching die 820 with respect to the die die 830 can be increased, the return of the section due to the punching can be prevented, and the speed of punching can be increased. it can.

(C) Since a pair of tension mechanisms 500 and 600 having lifting rollers 510 and 610 for relaxing and tensioning the workpiece W are provided, the lifting rollers 510 and 610 of each tension mechanism 500 and 600 are provided. The workpiece W is relaxed by ascending, and the workpiece W is re-tensioned by descending.

For this reason, it is possible to eliminate the meandering movement of the workpiece caused by the long-time feeding and winding operation, and it is possible to implement a good punching force.

(D) Since the imaging device 880 for reading the perforated position of the workpiece W is disposed on the center axis a of the through-hole 830A, the punching die 820 and the die are formed by the imaging device 880. The perforation position can be read within the plane of the mold 830.

Therefore, the horizontal movement time from the reading of the punching position by the imaging element 880 to the arrival at the punching position of the punching die 810 can be reduced, and the speed S of the punching process can be increased.

Further, since the perforation position can be read by the image pickup device 880 in a direction perpendicular to the workpiece W, the reading accuracy can be improved.

(E) The punching die positioning and fixing mechanism 900 has two positioning pins 920 and 921 that can be moved in the vertical direction. The positioning pins 920 and 921 are provided on the punching die mounting portion. The die 830 is provided with pin holes 830B and 830C which allow the positioning pins 920 and 921 to pass therethrough. The punch die 820 has , Pin fitting holes 820F and 820G are provided to allow positioning pins 920 and 921 to be fitted. Therefore, a simple operation of raising and lowering the positioning pins 920 and 921 allows the punch die 820 and die Positioning with the die 830 and positioning between the die mounting portion of the punch 800 and the die 830 can be performed with high accuracy.

Therefore, the positional accuracy between the punching die attaching portion of the punching device 800 and the punching die 810 is increased, so that the accuracy of the punching position on the workpiece W can be increased. In addition, since the positional accuracy between the punch die 820 and the die die 830 is improved, it is possible to perform clear perforation without returning the slice. Further, there is also an effect that a dedicated die position adjusting device for punching is not required, and the cost of the punching device can be reduced.

Next, a method for positioning and fixing the die for punching according to the embodiment will be described with reference to FIGS. FIG. 12 is a float chart for explaining a method for positioning and fixing the die for punching according to the embodiment. FIG. 13 is a plan view showing a spacer used to carry out the method for positioning and fixing the die for punching according to the embodiment. The method for positioning and fixing the die for punching according to the embodiment includes “a forming process for a die assembly for punching”, “a disposing process for a die assembly for punching”, and “attachment of a die for punching and a die for die”. Steps ”and“ Disassembly step of the die assembly for drilling ”are sequentially performed, and these steps will be sequentially described.

Note that the positioning pins 920 and 921 used in the method for positioning and fixing the die for punching according to the embodiment have the pin insertion holes 830B of the die for die 830 before the formation of the die assembly for punching. , 830C, and the upper end thereof is exposed above the die mold 830.

1. Forming Process of Drilling Die Assembly

First, a spacer P (shown in FIG. 13) having a thickness (eg, 395 μm) slightly smaller than the vertical dimension (eg, 400 μm) of the gap G (shown in FIG. 11) in advance. ) Is interposed between the punch die 820 (punch plate 823) and the die die 830 (die plate 832) to form a punch die assembly (step Sl in FIG. 12). At this time, the spacer P is placed on the die plate 832 by passing the positioning pins 920 and 921 through the pin holes P 1 and P 2. By placing the positioning pins 920 and 921 in the pin fitting holes 820F and 820G and placing the punching die 820 on the spacer P, a punching die assembly is formed. You.

[0077] 2. Arrangement process of perforation mold assembly

Next, the punching die assembly formed in the “step of forming the die assembly for punching” is interposed between the upper and lower mounting positions (mounting surfaces parallel to each other) of the punching mechanism 800 (shown in FIG. 5). (Step S2 in Fig. 12).

[0078] 3. Punching die · Die die mounting process

Next, by rotating the pin operators 930 and 931 (shown in FIG. 10), the positioning pins 920 and 921 are moved downward to fit into the positioning holes (not shown) of the table 722. Combine. Thereby, the force S for accurately positioning the die 830 with respect to the table 722 can be obtained. At this time, the positioning pins 920 and 921 pass through the pin through holes P and P of the spacer P, and are still fitted in the pin fitting holes 820F and 820G of the punching die 820.

1 2

You.

Next, the die die 830 is attached to the lower mounting position of the punching mechanism 800 by the chuck member 911 of the die positioning and fixing mechanism 900 for punching. In this case, since the die mold 830 is mounted by positioning the die die 830 with the positioning pins 920 and 921, the mounting accuracy is increased.

Next, after positioning the punching die 820 at the upper mounting position of the punching mechanism 800, the punching die 820 is mounted by the chuck member 910 of the punching die positioning and fixing mechanism 900 (step in FIG. 12). S3).

[0080] 4. Disassembly process of punching die assembly

Thereafter, by rotating the pin operators 930 and 931, the positioning pins 920 and 921 are further moved downward to release the fitting with the pin fitting holes 820F and 820G and the punching die is formed. The spacer P between the die 820 and the die 830 is removed (Step S4 in FIG. 12). Thereby, the die assembly for perforation is disassembled. At this time, the upper ends of the positioning pins 920, 921 are housed in the pin insertion holes 830B, 830C of the die 830.

When the spacer p is removed, the punch die 820 (punch plate 823) and the die die 8 A gap G set with high precision and high parallelism is formed between the gap G and the die 30 (die plate 832).

In this way, the punching die 810 is positioned and fixed with respect to the punching mechanism 800.

As described above, according to the method for positioning and fixing the die for punching according to the embodiment, the punching die 820 and the die for die are simply operated by moving the positioning pins 920 and 921 up and down. The positioning with the mold 830 and the positioning between the table 722 and the die for die 830 can be performed with high accuracy.

For this reason, since the positional accuracy between the table 722 and the punching die 810 is improved, the accuracy of the punching position on the workpiece W can be increased. In addition, since the positional accuracy between the punch die 820 and the die die 830 is improved, it is possible to perform clear perforation without returning the slice. In addition, there is also an advantage that a dedicated die position adjusting device for drilling becomes unnecessary and the cost of the drilling device can be reduced.

Further, in the method for positioning and fixing the punching die according to the embodiment, in the step of forming the punching die assembly, a pin is inserted between the punching die 820 and the die die 830. A spacer P having holes P and P and having a thickness of 0.1 mm

1 2

The die assembly for punching is formed by the above process, and in the disassembling process of the die assembly for punching, the spacer P interposed between the die for punch 820 and the die for die 830 is removed. ing.

[0083] In this way, the size of the gap between the punch die 820 and the die die 830 can be reduced to a range of 0.10mm-5. Omm by a simple method using only a predetermined spacer P. Can be controlled with extremely high accuracy. Further, since it is not necessary to separate the punch die 820 and the die die 830 so that a predetermined gap is opened, the parallelism between the lower surface of the punch die 820 and the upper surface of the die die 830 is extremely high. Can be expensive. In addition, when this force moves up and down the positioning pins 920 and 921, galling occurs between the positioning pins 920 and 921 and the pin through holes 830B and 830C and the pin fitting holes 820F and 820G. There is also an effect that it can be prevented from being performed.

[0084] This means that the dimensional difference between the inner diameters of the pin holes 830B and 830C and the pin fitting holes 820F and 820G and the outer diameters of the positioning pins 920 and 921 can be set to extremely small dimensions. It means you can do it. Thereby, the relative horizontal position accuracy between the punch die 820 and the die die 830 can be improved, which is effective in preventing the return of the section due to the perforation and speeding up the perforation.

[0085] As described above, the punching device, the punching die, the punching method, and the method for positioning and fixing the punching die of the present invention have been described based on the above-described embodiment, but the present invention is limited to the above-described embodiment. The present invention can be carried out in various modes without departing from the gist of the present invention. For example, the following modifications are possible.
